Dedicated Networks – Special Conditions for Telecommunication Equipment

It is not about:

Data Center environment

Constant temperature of +25°C

with 40% humidity

No dust

Continuous airflow

It is about:

Outdoor environment

Outside temperature of -50°C to

+ 50°C with up to 100% humidity

Dirty air

No airflow

Nevertheless we are transporting 10GbE and STM-16 with 99.999% reliability

Dedicated Networks – Main Requirements (1/2)

Critical services must be transported with

High availability

Fast convergence

Deterministic behaviour

Dedicated networks have been built and expanded for many

years – the results are

Complex network structures

Multitude of different equipment and management systems

Lots of existing services are still based on TDM technologies

Ethernet and SDH are the standard transport technologies

Maintainability and manageability is a key requirement

of 68 © KEYMILE

Dedicated Networks – Main Requirements (2/2)

Equipment must be hardened for harsh environments

Electrical sub-stations

Railway track-side installations

Outdoor deployment in outdoor housings

Facing migration to Ethernet

New services are Ethernet based

Old services changing towards Ethernet e.g.

Voice (e.g. TDM PBX to IP PBX)

SCADA (e.g. interfaces of sensors/actors changing from V.24/V28

towards Ethernet)

Migration of transport network from SDH to packet networks

Maintaining legacy equipment and services until swap to a

packet network is a must for the telecommunication system

Dedicated Networks – 3 Network Concepts for the new Requirements

aggregation (with core unit redundancy)

Extended operating temperature range for operation in harsh

environmental in outdoor housings

Different subrack sizes to accommodate different deployment

requirements

MileGate – General Platform Features

of 68 © KEYMILE

Provides smooth migration from TDM to Ethernet services as

well as from PDH/SDH to Ethernet transport networks

High availability of 99,999% (highest MTBF values, system

architecture with an all-embracing redundancy concept)

Supports fanless operation – no forced ventilation necessary

Support of critical TDM services with TDM to packet

interworking functionality

Fully managed with a flexible network management system

with offline configuration capabilities and interfaces towards

an umbrella management system

MileGate is ideal for networks that

are built-up with packet technology

expand on existing TDM technology

use both technologies simultaneously

MileGate – Ethernet Platform Features

of 68 © KEYMILE

Multiple Ethernet protection/load balancing mechanisms for

the transport network like RSTP, LACP, ERPS

IEEE switching approach with centralised switching function

64 Gbps wire speed Ethernet core (upgradeable by changing

core unit)

Extension of the number of Ethernet interfaces by inserting

units in the subrack

Behaves as one single integrated switch (called “chassis

switch”) with centralised

VLAN management

Spanning Tree implementation, supporting RSTP and MSTP

Other units with stand-alone switches can be included
